Question

Is there any alternative method to find the intensity of earth quake

Answer 1

The Richter Magnitude Scale is the method of earthquake measurement widely used in the  United States last century. Richter's idea was to track the amount of energy released by a quake the way an astronomer would measure the brightness of a star. Each number on the magnitude scale indicated an earthquake 10 times stronger than the last—which means the quake strength between each increment of one on the scale grows as the numbers climb.
